Today Glen and I finally figured out where we wanted to locate the pitot and oat lines,up the lighteneng holes and along the front of the spar which required us to remove the left fuel tank. Then we started riveting the right top inboard skin. Wasn't as difficult as we thought it would be, took us about 2 hours to finish the riveting. We hope to get the other 3 skins done by the end of tomorrow. Glen also prepped and sprayed with primer the aileron gap seal. Also Glen worked on the wiring for the aileron trim and is now complete.
